Cellular respiration is the process by which cells in the body produce energy in the form of ATP (adenosine triphosphate). This process occurs in the mitochondria, the powerhouses of the cell, and involves a series of chemical reactions that convert glucose (a simple sugar) into ATP. During cellular respiration, several substances are released as byproducts, including water, carbon dioxide, and heat.
One of the substances released during cellular respiration is water. Water is produced as a byproduct of the breakdown of glucose during the process of glycolysis, which is the first step of cellular respiration. During glycolysis, glucose is broken down into two molecules of pyruvate, releasing energy and producing two molecules of ATP in the process. The pyruvate molecules are then further broken down in the mitochondria, releasing more energy and producing more ATP. As part of this process, water is produced as a byproduct of the breakdown of glucose and pyruvate.
Another substance released during cellular respiration is carbon dioxide. Carbon dioxide is produced as a byproduct of the breakdown of pyruvate in the mitochondria. During this process, pyruvate is converted into a molecule called acetyl-CoA, which is then used to produce ATP through a process called the citric acid cycle (also known as the Krebs cycle). As part of the citric acid cycle, acetyl-CoA is broken down into carbon dioxide, releasing energy and producing more ATP in the process.
Heat is also released during cellular respiration, as a byproduct of the chemical reactions that produce ATP. The energy released during these reactions is partially converted into the form of heat, which is then released into the surrounding tissue. This heat production is an important part of the body's thermoregulation, helping to maintain a constant body temperature.
In summary, water, carbon dioxide, and heat are all substances that are released during cellular respiration, as byproducts of the chemical reactions that produce ATP. These substances are important indicators of the efficiency of cellular respiration, and their production and release is carefully regulated by the body to ensure that the cells have a constant supply of energy.

B They would be converted to pyruvate and then undergo pyruvate oxidation upon transport into mitochondria. Curiously, the consumption of sugar increases as oxygen is removed from the organism's environment, even though the organism does not gain much weight. It takes more energy to make ATP from ADP and Pi using FADH2 than using NADH.

This assumes that the sizes of each component are different and do not overlap. When electrons flow along the electron transport chains of mitochondria, which of the following changes occurs? Exposing inner mitochondrial membranes to ultrasonic vibrations will disrupt the membranes. Plants carry out cellular respiration only in organs such as roots that cannot carry out photosynthesis.

Which one of the following statements about the redox reactions of the electron transport chain is correct? The chemiosmotic synthesis of ATP requires that the electron transport in the inner mitochondrial membrane be coupled to proton transport across the same membrane.
D It is a photosynthetic organism. Cellular respiration is a metabolic process consisting of a series of steps to convert chemical energy sugar into a usable form of energy ATP in the cell. First, however, the pyruvate 1 loses a carbon, which is given off as a molecule of CO2, 2 is oxidized to form a two-carbon compound called acetate, and 3 is bonded to coenzyme A. D Other cells take over, and the muscle cells that have used up their ATP cease to function. D They would have elevated blood-glucose levels, which may result in a high incidence of diabetes.

In the presence of oxygen, the three-carbon compound pyruvate can be catabolized in the citric acid cycle. What two major processes are involved in the cycling of carbon? Note that you should not consider the effect on ATP synthesis in glycolysis or the citric acid cycle. Oxaloacetate will decrease and citric acid will accumulate.
